Walter’s Face, Shoulder and Slot Drill Milling Cutters Reduce Cutting Forces

(Waukesha, WI) — Walter has introduced the MP060, MP160 and MP260 face, shoulder and slot drill milling cutters with brazed PCD cutting edges, a new suite of products for machining aluminum, Al-Si alloys, magnesium and magnesium alloys, as well as composites and plastics. These new milling cutters offer significant benefits, primarily with respect to their service life, surface quality and efficiency.

The MP060 face milling cutter with a great number of teeth (z) between 10 and 22, and with diameters from 40 mm, can be used for roughing and finishing large surfaces and flat shoulders. The MP160 (z = 3–4) and MP260 (z = 2–3) shoulder and slot milling cutters, with either cylindrical shank or ScrewFit adaption and diameters of 16–40 mm and 4–20 mm respectively, are suitable for smaller flat surfaces, for plunging (MP260) and full slotting, as well as, in the case of the MP160, ramping, drilling and re-drilling work. All three milling cutters are equipped with internal coolant supply and can be used with emulsions and minimum quantity lubrication.

The service life of these new milling cutters, which is significantly longer than that of solid carbide tools, is primarily the result of the wear-resistant WDN20 Walter grade, as well as reduced cutting forces and low-vibration microgeometry. Their precise machining, combined with the internal coolant supply, enables users to produce high-quality surface finishes. In addition, relatively low cutting material costs, fewer tool changes due to the longer service life, and the fact that the milling cutters can be reconditioned (diameters of 6 mm or more) also increase the tools’ service life. These new Walter milling cutters are particularly well suited for the automotive, electronics and general metalworking industries.
